LOOSE-LEAF BINDER.

Specification of Letters Patent.

Application filed December 19, 1910.

Patented A11 22, 1911.

Serial No. 598,114.

To all whom it may concern:

Be it known that I, \VILLIAM C. LOUD, a citizen of the United States of America, residing at Detroit, in the county of \Vayne and State of Michigan, have invented cer tain new and useful Improvements in Loose- Leaf Binders, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to loose-leaf binders, and more especially to that class thereof in which the leaves have marginal perforations through which the hool-:-members of the binders pass and permit free access to and .inspection of the leaves, and it has for one of its objects: the provision of simple and effective device of this character which may generally be opened only for a certain amount without disengaging the leafretaining fingers, and which may be opened farther to insert or remove loose leaves only subsequently to the manipulation of the lockmember of the device, whereby the latter may also be locked in its closed-in condition. The invention has furthermore, for its object the provision of a novel hinge the pin of which controls the amount of opening of the device.

Further objects of the invention will hereinafter appear and be defined in the claims.

The invention has been clearly illustrated in the accompanying drawings, in which similar characters denote similar parts, and in which Figure 1 represents a fractional top view of a temporary binder embodying my invention, in closed but unlocked condition; Fig. 2 is an end view thereof; Fig. 3 is a top view showing the binder opened to permit the leaves being turned over for inspection; Fig. 4t is an endwise View of the same; Fig. 5 represents a top view illustrating the binder spread open to permit leaves to be inserted or withdrawn; Fig. (3 shows an end View thereof; Fig. 7 is a view corresponding to Fig. 1, but illustrates the binder locked; Fig. 8 shows in detail the locking hingerod of the device, and Fig. 9 illustrates one of the hingc sections with its multi-part slot.

The present device consists of only three movable parts, viz. the two finger-carrying plates, and the hinge-rod whereby they are jointed.

In the drawings, the numeral 10 denotes one of the hinge-plates having one of its longitudinal edges cutout to form rolled-over hinge-journals 11, which are interposed between similar journals 12 of a hinge plate 13, a rod l i passing through all the journals and jointing the plates for pivotal movement. The plates l0, [3 are provided with arcuate lingers 10, '13, respectively, adapted to telescope into each other, as shown in Fig. 2, and concentric with the hinge-rod 14.

In the present instance the device is adapted to be locked against further opening movement in three distinct positions shown in Figs. 1 and 7, and 3 and 5, respectively, the rod 14 constituting the medium whereby the result is etl'ectcd in a positive manner.

liy referring to Fig. 1 it will be seen that the journal 12 has a slot comprising three steps or notches 15, 15', 15", within which a feather projection 10 is movable as controlled by the longitudinal movement of the rod l-t to which the feather 16 is attached or of which it may be an integral part as illustrated in Fig. 8. The rod 14: has also another feather 1.7 which is adapted to be positioned in notches l8, 18, 18" of a slot formed in the adjacent journal 11 of the other plate .10, the complete slots being substantially right and left; hand as can be readily seen by a comparison thereof in Fig. l, in which the notches l5 and 18 are substan tially in alinement, and therefore adapted to receive the feathers 1(3, 17, respectively, of the rod l--l-, (see Fig. 7), in which position the two plates are positively lOCh'Od against swinging movement relative to each other. \Vhen now the rod ll is pulled downward to the position shown in Fig. 1 (by the handle end it), viz: so as to bring the feathers 16, 17 into the notches 15, 18, both plates may be swung away from each other into the position shown in Figs. and i, where the lingers l0, 13 are still in engagement, and now permit the leaves to be turned over as usual for inspection without crowding, and by virtue of the increased are. It will be noted that the plates are here locked against further opening movement. However, when the rod 14 is pulled downward to bring the feathers l6, 17 into the notches 15", 18', the plates may be opened to the limit: as shown in Figs. 5 and (3, in which the ends of the fingers 10', 13 are spaced to permit ready insertion or removal of leaves therefrom. As in some instances, it

may become desirable to lock the plates in their wide-open position, the notches 15", 18 may have branches 15 18 just deep enough to permit the feathers 16, 17 to be drawn thereinto, in which case both plates would be positively locked against movement in either direction, a condition which also exists When the feathers are in the necks connecting the notches 15, 15", and 1s, 1s".

From the foregoing it will be understood that my improved binder consists of the fewest number of parts possible and that it is adapted to perform its work in a very satisfactory manner.

Many changes may be made in the particular construction and organization of the several elements of my improved device, without departing from the spirit of'the invention especially as to the shape of the locking slots, or the locking rod, and the fingers.

I claim:

1. A loose-leaf binder comprising a pair of plates laterally movable toward and away from each other and having interlocking portions provided with opposed slots, fingers on said plates, and a longitudinally slidable device in engagement with both of said plates and having feathers entering said slots, and for controlling their position relative to each other.

2; A loose-leaf binder comprising a pair of adjacent plates having interlocking hingeportions provided with opposed slots, fingers 011 said plates, and a hinge-rod in longitudinal sliding engagement with said hingeportions and having feathers in said slots, respectively, for controlling the angular position of said plates relatively to each other.

3. The combination with a pair of adjacent finger-plates, each having a rolled-over hinge journal overlapping and in axial alinement with the other hinge-journal, said journals being provided with longitudinal opposed slots, of a hinge rod longitudinally movable in said journals, and feathers on the rod and in said slots, respectively, for locking said plates against opening from a predetermined position.

4. The combination with a pair of adjacent finger-plates, each having a rolled-over hinge journal overlapping and in axial alinement with the other hinge-j ournal, said journals being provided with longitudinal opposed slots each composed of a series of connected notches angularly disposed around the axis of the journals, of a hinge-rod longitudinally movable in said journals, and feathers onthe rod and in said notches, respectively, for locking said plates against opening from a predetermined position.

In testimony whereof I aflix my signature in presence of two witnesses.
